According to

Put your finger on the capaciative scanner and the ridges will cause some plates to come into contact, thereby closing a circuit and generating current, while the cells under the ridges on your fingers remain separate. The system then interprets the voltages generated by each cell to determine which one is under a ridge and which is under a valley. By combining this data the scanner can generate an overall image of the print, much as an EO scanner would, but with a much higher degree of fidelity.
